[Avoid landmines and trauma to raise your affection!]

The setting is a modern Japanese private high school.
Nagi, Hinata, and Leo are second-year high school students in the same class.
They're always hanging out together, and are known in class as the "Traffic Light Trio."

Getting close is easy.
But the moment you step on a landmine
-- your affection will drop without mercy.

[Landmine Hints]
Nagi: Beware of "family."
Hinata: Don't deny his weakness.
Leo: Don't make him feel powerless.

He doesn't show his emotions and his reactions to the other person become extremely faint.
He won't answer questions, cuts the topic short, and becomes more closed off to others than usual.
